a corporation of New York v s Application April 21, 1948,, Semitic, 22,423 I 1 This inventionrelates to the winding of sheet material about cylindrical bodies and is especiallyuseful in the manufacture of fabric reinforced rubber hose or similar articles or similar operations where adhesive. sheet material is to be wound about an elongate mandrel or pole.

In the manufacture of rubber hose, where an elongate mandrel has been supported upon driven cradle rollers and pressure has been applied thereto by a superimposed pressure roller while adhesive sheet material has been fed between the mandreland the supporting cradle rolls, difficulty has been encountered in handling the mandrels with the wrapped articles thereon because of the length and consequent weakness of the mandrels resultin'gin sagging and permanent bending of the mandrels where it has been attempted. to lift them to and from the winding apparatus by their ends. mandrels have resulted in damage to the hose, It is an object of the present invention to avoid those difficulties by providing for support of the mandrel's' at positions throughout their lengths to avoid sagging. l I

Other objects are to provide for rapid. discharge of the wrapped article from the wrapping apparatus, to provide for deposit of the article upon supporting runways, and to provide for lifting the articles to an elevated position for. delivering to a position for] further treatment. s

Theseand other objects. will. appear from: the

Furthermore, attempts to handle the role-1m (Cl. 2425-66) 1 following description, reference being had to the accompanying drawings which show an embod-iraised position and the article supported by the.

pressure arms, the dot and dashlines indicatingthe position of the arms in discharging the article to the runways.

Fig. 4 is a sectional view, taken on line 44 of Fig. 1 showing the mechanism for driving the cradle rolls.

Referring to the drawings,. the numerals lll,

ll, 12 designate similar vertical frame members arranged at spaced-apart intervals. The frame members are attached to the floor and held in spaced-apart relation by suitable tie rods (not shown). Arranged in aligned bearings l3, l4, I5.

secured to frame'me'mbers I0, I I, I2 is a rotatable shaft I6. A. second shaft I'l, parallel thereto, is rotatablysupported on the frame members by bearings l8, i9, 20 thereon. Fixed to shaft [1 are series of segmental gears 25, 2'6, 21. Fan-shaped arms 28', 2Q, 30 are rotatably mounted upon shaft lfi and have segmental gear portions 3! meshing with. gears 25, 2'6, 21. A pair Of elongate cradle'rolls 34",. 35 aresupported for rotation on the arms 28, 29, 36 as by anti-friction rollers 36, 31, 38 mounted thereon. Fixed to one end of shaft [1 adjacent the frame member i2 is a segmental gear 32. A double-acting fluid pressure cylinder 33 is secured tothe frame member l2 and its piston rod H, which extends vertically, has a rack 13 secured thereto and meshing with gear 32. The arrangement is such that when the rack 13 is in lowered position, the cradle rolls 34, 35 have their axes in a horizontal plane, as shown in Fig. 2, where they are in position to support and retain an elongate rotatable article 4|, and in the raised position of the rack- I3, the axes of cradlerol'ls 34, 35 are in an inclined plane, as shown in Fig. 3, such that the article will not be retained but will roll off of the cradle rolls.

The arms 28, 29, 30 havestopposi'tions 40 which in the lowered position of rack 38 rest upon the frame members Ill, 1 I I21 respectively to level the cradle r0'1ls34, 315. r l i Provision is made for driving the cradle rolls 34. 35 and for this purposea gear supporting member 42 (see Fig. 4) is pivctally mounted on shaft l6. The ends of cradle rolls 34,- 35 are rotatably Journaled in this member and have pinions 43, 44 fixed respectively to their ends. clear each other. ear. 45 is fixed to shaft It and meshes with pinion 43m A similar pinion 43 meshes with-gear and. is rotatably mounted about a stud 41 fixed tomemberllz. An idler gear 48 is rotatably mounted on a stud 49 fixed to members, 4-2, and meshes with pinions 44, 46.

The arrangement is such that cradle rolls 34,35

are driven in the same direction by shaft 16 at any position of the cradle rolls. A sprocket 50 is securedto shaft t6 and-engages a drive chain 5!, driven from any suitable source f power (not shown). l 1

Provision is r made for holding. the article against the cradle rolls, and for this purpo'sea shaft is journaled in bearings 56, 51, 58 mounted on frame members ill, ll, [2 respectively. Arms 59, 60, 61' are fixed to shaft 55, p

which also has a pinion 62 secured thereto. A double-acting fluid pressure cylinder 65 is fixed vertically to frame member l2. Its piston rod 66 These gears 3 has a rack 61 secured thereto which meshes with pinion 52. The arrangement is such that when the rack 67 is raised, as shown in Fig. 2, the arms 59, 69, 6! are in substantially horizontal position, and where the rack 61 is lowered, as shown in Fig. 3, the arms are raised. The arms 59, 69, 6| are formed with notches 68 for retaining a pressure roller t9, anti-friction rollers 70 being provided for engaging the roller. The notches are so formed that the roller cannot drop from them but one face of the roller is exposed for pressing purposes.

The arms 59, 60, 6| are also formed with catching means such as the hooked extensions 15 having concave seats facing upwardly in the horizontal pressing position of the arms and located slightly below the top of the cradle rolls 34, 85 so that when arms 28, 29, 39 are rotated'about shaft it; in a counter-clockwise direction, as seen in Fig. 2 to the dot and dash line position, the article M will be deposited on the extensions 75, and upon rotation of arms 59, B0, 6! in a counterclockwise direction, as seen in Fig. 3 the article will be deposited upon conveyor means such as inclined runways 76 attached to and extending away from the frame members [0, H, [2, the final rotative position of arms 59, 60, iii being shown in dot and dash lines in Fig. 3;

The article ll rolls down the inclined runways to a position for performing another operation thereon. By lifting the article and depositing it on the inclined runway at a higher elevation than it assumed during the winding operation the article is transferred by gravity from the machine to the next operation withoutlosing altitude, thereby keeping succeeding winding operations at the same attitude with respect to the operators.

In the operation of the apparatus, the arms 59, 63, Si are raised and an elongate mandrel is laid upon the cradle rolls 34, 35, the rolls 34, 35'are rotated by the rotation of shaft [6, and the arms 59, 99, iii are'lowered to the position illustrated in Fig. 2. For this purpose fluid under pressure is admitted to the lower end of cylinder 65 through a suitable control valve. 7 Sheet material is then fed over a table 11 and between the mandrel and cradle rolls where it is adhered to the mandrel and is wound thereabout raising the roll $9 as the article increases in diameter. 7 When the article is completed, the operator adjusts a valve which controls cylinder 33 so as to cause fluid under pressure'to enter the lower end of the cylinder, rotating the arms 28, 29, '30, in a counter-clockwise direction about shaft l6 and depositing the wound article and mandrel on the hooks l5. Thereafter the operator rotates arms 59, 90, 6! in a counter-clockwise direction'about shaft 55 by admitting pressure fluid to the upper While three of the frame members with their associated mechanism have been illustrated, it is to be understood that this mechanism may be duplicated for handling extremely long lengths of hose or other long articles requiring continuous support.
